	<h2>Console: Creating a universal Console</h2>

	<div id="example" class="promo">
	<p>
	<p>In this example, the Console's <code>logSource</code> configuration is set to <code>Y.Global</code>, an <code>EventTarget</code> shared by all YUI instances.</p>

<p>Two YUI instances are created with different configurations and module inclusions.  Each YUI instance is configured to request the <code><em>module</em>-debug.js</code> version of its modules and dependencies and filter out all but specific log sources using the <code>logInclude</code> config property.</p>

<p>The universal Console is instantiated and rendered inside the first YUI instance.</p>

	<h3 class="first">Multiple YUI instances</h3>
<p>Each YUI instance is its own sandbox.  You can create as many YUI instances on a page as you want or need.  The variables, module configurations and instances are kept inside that instance unless you expressly expose them via a global variable.</p>

<h3>Listening to <code>Y.Global</code></h3>
<p>To address debugging such an environment, Console can be configured to listen for log messages across all YUI instances by setting the Console instance's <code>logSource</code> configuration to <code>Y.Global</code>.</p>

<p>We'll insert the Console creation into the first YUI instance's callback.  By default, Console will only listen to log messages originating from its own YUI instance sandbox.</p>
